The braces l2 bolt 34 extends. A thumb nut 35 is carried by are in the nature of uprights or standards which the bolt 34 for the purpose of securing the guide have forwardly extending overhanging end porsupport 38 in an adjusted position upon the plat- .55 tions i4, and these end portions l4 carry the form II. This guide support 30 may be adjusted 55 A still further object of this invention is the picker element being preferably provided with to or from the edge of the platform II, by sliding the slot portion 33 over the bolt 34 and then tightening the nut 35 to the adjusted position. The guide support 38 carries an upstanding pin 36 upon which is mounted a coil spring 31 and the pin 36 is seated within a socket cup 38 carried by the under face of the table 25, the spring 37 engaging the lower edge of the cup 38 and normally urging the table 25 upwardly. Due to this structure, a resilient support will be provided for the sole of the shoe and the operator may assist in providing the pulling action for the picker elements 22 by pushing downwardly upon the sole of the shoe which rests upon the spring pressed table 25, the spring 3'! normally returning the table 25 to its extended position.

From the foregoing description it will be seen that a very simple and eflicient stitch remover has been provided in the nature of the picker elements 22 and also in conjunction with the spring pressed table which supports the shoe yieldably against the action of the picker elements. Furthermore, it should be understood that a very durable and sturdy spring pressed supporting element has been provided upon which the sole of the shoe may rest, this support being also adjusted to the various widths of soles to facilitate the gripping of the stitches by the beak-like ends of the picker hooks 23. In carrying out this invention, the sole is first cut from the welt, and the device above described may then be used for pulling or removing the stitches from the welt.

It should be understood that certain detail changes in the mechanical construction, combination and arrangement of parts may be employed without departing from the spirit of the invention, so long as such changes fall within the scope of the appended claims.

Having described the invention, what I claim as new is:

l. A device of the class described comprising an angle guide support having a vertically extending member and a horizontally extending member, the horizontally extending member being longitudinally slotted, an anchoring bolt passing through the slot portion of the horizontally extending portion, means engaging the bolt for locking the guide support in an adjusted position, a table member having a depending leg slidably engaging the vertically extending portion of the guide support, a guiding pin carried by the guide support and engaging the table member, and spring means interposed between the table member and the guide support for yieldably supporting the table member.
